Extension and exact realization of the Heller's derivative rule

Mathematical Physics 2017-10-03 v1 math.MP

Abstract

The accuracy of the Heller's derivative rule to calculate the numerical weights associated with discretized energy spectrum is enhanced by Broad's extension which adds (N-1) more interpolating points to the original N points. The extension scheme is then used to show how to realize the rule without any approximation.
